SPECIFICATION forming part of Letters Patent no. 700,541 dated Ma/20,1902.-

Application filed August 31, 1901. berial No, 73,971. v (No model.)

- To all whom it may concern:

Be it known that I, HoRAonB. MURDOCK, a citizen of the United States,residing atDetroit, in the county of \Vayne and State of Michigan, .haveinvented certain new and use-.

ful Improvements in Plow Attachments; and I do hereby declarethefollowing tobe a full, clear, and exact description of the invention,

such as will enable others skilled inthe art to which it appertains tomake and use the same. My invention relates to improvements in plows,and especially to an improved attach ment to be secured to the beam ofthe ordi nary'type of plow for regulating the move ment of theplow-point for making a furrow of an even depth.

Another-feature of myinvention resides in the provision of a means formaking the furrows in parallel lines and spacing them at a predetermineddistance apart.

To more fully describe my invention, ,referonce is had to theaccompanying drawings, in

Which-- with my invention appliedthereto. Fig. 2 is a sectional viewthroughthe plow-beam and attachment. the axle supporting the outerwheel. Fig. 4'

Fig. 3 sh'ows'a modification of is a side elevation of one of theaxle-hangers, partly in section and showing the manner of securing thesame to-theaxle. Fig. 5 is a longitudinal section through the plow-beamat the point where the attachment is secured and showingaslightly-modified form of side clamp, and Fig. dis a planview of themodi fied form of clamp shown in. Fig. 5.

A is a plow of any of the well-known types. To the beam B of the plow Isecure my im:

proved attachment, the same being both vertically and longitudinally adjustable with re-; This attachment spect to the plow-beam. consistsof'the-two angle-irons O 0, having a series of perforations c 'throughtheir vertical webs, constitntingthe hanger-bars for supportingjtheaxles of-the guiding-wheels D and D. The horizontal web of theaxlehanger O is suitably rounded off and constithe axle d of theouterwheel D, which axle d is provided with a series of perforations dthrough which the bolts E are adapted to pass, thus permitting thelateral adjustment (of the axle cl in respect'to the plow for regu- Thevlating the distance between furrows. wheel D is rounded'ofi, as at d onthe inside of the tread to prevent cutting into the ground. When it isdesired to use a smaller outer wheel instead of using the straight axlecl, an axle of such a constructionas shownin Fig. 3 might be used. I

F F are clamps on each side of the plowbeam, to which the axle-hangers Cand C are adjustablysecured through the medium of the lugs f, whichengage inthe perforations 0 of the hangers. These clamps F F are heldfirmly in position by-the. tie-bolts G and G,

which pass above and beneath the plow-beam and support and firmly holdthe various parts in place. v

In Figs. 5 and 6 I haveshown a slight modification of these clamps. .Inorder to reduce the lateral strain on the hangers G O, I provide thelower ends of the clamps F F with the inwardly-projecting lugfflwhich isbent to restfagainstthe' inner faces of th'e' hangers O O. V

In order that my improved device might the more readily be attached to,a' plow-beam of any heightand for, the purpose of the more securelyclamping" the attachment to the beam, I provide the wedgeH, having aninclined corrugated surface, in' the grooves h of which the uppertie-bolt G is adapted to be supported. As this wedge can be forced theattachment to the beam.

The'upright webs of the axle hanger-bars '0 0'. and the sideclamps-FFare preferably made of channel-iron bars for the purpose ofsecuring lightness in construction.

"along the plow-beam, it is readily seen that it provides a very securemeans for fastening noted that the axle on which the larger outer wheelD is mounted is laterally adjustable,

which allows the wheel D to be moved in toward or away from the plow,thus regulating the distance between the furrows. The smaller innerwheel D always remains in the same relative position to the plow. Bothof these wheels D are adjustably mounted in the vertical plane throughthe medium of the axle-hangers C and C, which permits of their beingraised or lowered to regulate the depth of the furrow to be plowed.

Although I have described my invention as applied to plows for thepurpose of plowing fields in furrows, it is obvious that my improveddevice is applicable to plows used for the purpose of plowing over thewhole surface. This is readily accomplished by the proper adjustment ofthe outer wheel D with respect to the plow-point.

I do not wish to limit myself to the exact details of construction asdescribed, as it is obvious that many modifications might be madewithout departing from the spirit of my invention.

Having thus described my invention, what 1 claim, and desire to secureby Letters Patent of the United States, is

1. The combination with a plow,ofahangerbar carrying a wheel mounted onone side of the plow-beam, a second hanger-bar provided with a groovedhorizontal web mounted on the opposite side of the plow-beam, an axle,carrying a wheel, engaging the groove in said horizontal web, means foradjusting said axle laterally in said groove, and means for clamp ingsaid hanger-bars to the plow-beam.

2. The combination with a plow, of a pair of clamps located on each sideof the plowbeam, a pair of hanger-bars secured between said clamps andplowbeam ,one of said hangerbars having an axle formed integraltherewith for carrying a wheel, the other said hanger-bar provided witha grooved horizontal web provided with bolt-holes, a perforated axle,carrying a wheel, engaging said groove, the perforations in said axleadapted to aline with the bolt-holes in said horizontal Web for securingthe lateral adjustment of said axle.

3. The combination with a plow of a pair of perforated hanger-barscarrying wheels located on each side of the plow-beam, clamps havinglugs engaging in said perforations, and tie-bolts for tying said clampsand axlehangers together on the plow-beam.

4. The combination with a plow of a pair of hanger-bars carrying wheelslocated on each side of the plow-beam, clamps engaging said hanger-bars,tie-bolts mounted above and beneath the plow-beam and engaging saidclamps, and a wedge adapted to be inserted between said upper tie-boltand plow-beam for securely attaching the said hanger-bars to theplow-beam.

5. The combination with a plow, of a pair of hanger-bars carrying axlesand wheels located on each side of the plow-beam, clamps engaging saidhanger-bars, tie-bolts mounted above and beneath the plow-beam andengaging said clamps, and a corrugated wedge adapted to be insertedbetween said upper tiebolt and plow-beam for securely attaching the saidhanger-bars to the plow-beam, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
